Bret Michaels puts more effort into covering up his scalp than most Rock of Love contestants do with their breasts or crotches. What's a goin' on under that bandanna?

Last April, Bret said that his hair is "combined of my [natural] hair and the finest extensions Europe has to offer. I do the show without [the bandanna] on all the time and they won't film me. They are like, 'Put your bandanna back on. It is your image.' It is my signature thing."

We did some investigating, and that shit doesn't look like extensions, but a straight-up wig - one that seems to be getting fuller, longer, and waxier as time goes by. Let's take a look at two decades worth of Bret's hair.

We know what he used to look like back in the day, when all he needed was some hairspray and a pick to get such volume.

But there has been a clear evolution in wig thickness just over the course of the three seasons of Rock of Love.

It's now flowing.

This is probably the closest thing to his real hair, circa 2001.

And circa 2004.

These extensions from 2005 are very realistic.

But he quickly moved onto this look.

Which somehow turned into Fergie-with-a-goatee.

He has attempted to go sans bandanna a few times over the years, but the results are decidedly unfavorable.

This is our guess at what the true texture and thickness of his natural hair would be.
